I can't help you on the XP setup - I got rid of windoze before they
discovered the concept of networking.

I'll take your word for it

You know, we shoot people for puns like that ;-)

That might need to be 'Yes'

Hopefully it knows what's going on. Can it talk to the world?

That may be reasonable for the Internet side

I don't do windoze, but this doesn't sound exactly correct. The default
should be some host on the same network as 69.151.200.34 (the Internet)
and the DNS server should be something outside as well. When I ask my
name server about 69.151.200.34, it refers me to ns1.swbell.net at
151.164.1.1, and ns2.swbell.net at 151.164.11.218. They may or may not
be the DNS server you need to use.

What does '/sbin/ifconfig -a' and '/sbin/route -n' show on the Linux boxes?
Let's assume they are on 192.168.10.0/24 with addresses 192.168.10.2 and
192.168.10.3. Let's further assume the windoze box has the second NIC as
192.168.10.1. 'ifconfig' should show "my" address, right mask, network
and broadcast, and little or no error counts. Perhaps something like
eth0 Link encap:10Mbps Ethernet HWaddr 02:60:8C:57:C0:F7
inet addr:192.168.10.3 Bcast:192.168.10.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:100907 errors:0 dropped:0 overruns:0 frame:0
TX packets:92050 errors:0 dropped:0 overruns:0 carrier:0
collisions:154
Interrupt:10 Base address:0x300
The routing table should show the local route AND a route to the world,
using the windoze second NIC as gateway - perhaps
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 89948 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 388 lo
0.0.0.0 192.168.10.1 0.0.0.0 UG 0 0 2673 eth0
The windoze data (ipconfig is one, 'route print' for the other) is going
to have to show similar concepts - except that the 'default route' to
the world will be pointing out the DSL interface at some outside box.

What do you need to talk to the windoze box? OK - it's in the first line,
so send things directly. What do you need to talk to the world? Well,
the world isn't connected to this wire, so send the packets to the
windoze box for forwarding.

My guess - yes

Have you looked at the HOWTOs? You haven't told us what the Linux
distribution is, so we can't tell you what files to stroke, or what
GUI icon to click on - that would help.
